Niobium Circles Cuff

ONE-OF-A-KIND: This sterling copper cuff is enhanced with a two-tone green anodized niobium* band that has been embossed with a bubbles pattern and sterling silver bubbles attached to it. The cuff is 3/4 inch wide and is adjustable to fit most wrist sizes. * Niobium (Nb) is a reactive metal similar to titanium. An electrical current passed through it will change the surface color (anodized). The amount of voltage applied will determine the color. It is hypoallergenic because it is resistant to acids and alkalines. To clean, if it loses it’s shine, use any window cleaner. It costs about the same as sterling silver and is a bit lighter in weight. While the anodized color should not fade, it is a surface color and can scratch but not readily.
